Jaundice is caused by a buildup of bilirubin in the blood, which causes yellowing of the skin and eyes. Herbal remedies for jaundice work by stimulating liver function and increasing bile flow to excrete bilirubin from the body. Common causes include viral infections like hepatitis, alcohol use, autoimmune disorders, and certain medications. Symptoms are fever, abdominal pain, flu-like symptoms, and yellowing of the skin and urine or pale stool.
